To all whom it may concern Be it known that I, THOMAS F. BARTON, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented new and useful Improvements inGutside Flush Doors for Box-Cars, of which the following is aspecication.

The object of this invention is to provide a box car with a flushclosing door of simple andr inexpensive construction, comprising but fewparts which can be readily assembled, and adapted to be easily closedand Opened.

In the accompanying drawings illustrating one embodiment of theinvention, Figure 1 is an elevation of a portion of a box car showing myimproved door closed. Fig. 2 is an enlarged detail sectional view on theline 2 2 of Fig. 1. Fig. 3 is an enlarged detail view of a dog bearingbracket. Figs. 4 and 5 are vertical sectional views showing the car doorin open and closed positions, respectively. Fig. 6 is a detail rear viewof one of the hangers. Fig. 7 is a transverse sectional view showing theconstruction of one of the door posts.

The door 8 is constructed to fit snugly in an opening 9 in the side ofcar 10 and its lower edge 8 may be beveled to fit against the bevel edge10 of the floor of the car at the bottom of the opening 9. Hangers 11are provided with rollers 12 which travel on a track 13 suitablysupported on the car above the opening 9 and inclosed within a hood 14.Each hanger is provided, below the track, with an angular part 15 havinga slot 16 inclined upwardly from the front of said angular part to therear thereof and extending transversely therethrough, and also anotherslot 17 (Fig. 6) in the rear face of said angular part which intersectsthe slot 16. A plate 18 is fastened on the front of the door, at the topthereof, and this plate has a T-head 19 and a contracted neck 20. Thehead of the plate 18 is engaged with the slot 16 and on both sides ofthe slot 17. When the door is open the heads of the two plates 18 willrest in the lower ends of the slots 16 (Fig. 4) and in closing the doorthe heads will slide upward in these slots and guide the door intoclosed position (Fig. 5).

The hanger and plate provide a two-part means of simple construction andadapted to be readily assembled for suspending thedoor from the track.In assembling these parts the hangerV is arranged on the track and theT-head of the plate 18is turned so that it can be inserted through theslot 17 and is then turned to rest in the slot 16 of the hanger, asshown in Fig. 4, after which the plate is bolted or otherwise fastenedto the door. While the parts can be readily assembled inthe simplemanner just described. it will be observed that the hanger and plate cannot be disengaged without first unfastening the plate from the' door andthus the partsare secured together in a simple and secure manner.

A cross bar 21 is secured on the door by brackets 22 and held againstlateral movement by collars or shoulders 23 thereon which engage thebrackets. A handle lever 24 is made rigid with this cross bar at orabout the middle thereof and it is provided with a slot 25 and carries ahook 26 to engage a staple 27 on the door which projects through slot 25when the handle lever is thrown to closed position (Fig. 5). A dog 28 isrigidly mounted at each end of the cross bar and projects at rightangles to the cross bar. Each dog is arranged toenter a socket 29 in thedoor posts BOand over the sockets there is a facing plate 31, thelongitudinal axis of the bar 21 being preferably located above the baseof the socket opening when the door is in open position. I may providethe dog with a shoulder 2S to engage the facing plate at 31 (Figs. 3,2). When the handle lever is thrown down the dogs will be carried out ofthe sockets 29 and the door will move out of the opening 9 into openposition (Fig. 4). In closing the door the handle lever is swung upwardand the dogs will engage the bearing edges 31 of the facing plates sothat the door can be lifted and moved into closed position.

In this position the dogs engage both of ,theY

the door from the track, said means com-- prising a hanger to travel onthe track and having an angular part beneath the track, said angularpart of the hanger having a transverse slot extending upward andintheren, and means for fastening the plate Ward from the bottm to thetop thereof to the door below the henger.

and :L slot in its unc ersde which intersects T said transverse slot,zrplate having a con- THOMAS F' BARTON treated neck and a T-head, saidhead being Vtnesses: adapted to be inserted through saidv inter- VWM.
